Voltage measurements of hybrid engines

In the automotive field, hybrid drives are becoming increasingly interesting. This type of system not only has a conventional internal combustion engine, but also an electric motor.

The power of the electric motor and the recovery during braking is done via batteries.

A measuring problem arises when measuring individual, cascaded cell voltages. While the cell voltages are typically only a few volts, connecting the cells in series produces a high voltage level on the basis of which the cell voltage must be measured.

This whitepaper indicates what to look for in performing such measurements and helps in selecting the appropriate measurement amplifier.
